If David Ellis wants to put a halt to development and preserve green wedge that he considers to be valuable, then he should organise a coalition of like-minded people and buy the land so that it remains untouched.
Environmentally concerned activists in other countries have been known to put their money where their mouth is and buy land from developers in order to prevent unsightly construction.
I believe this sort of voluntary cooperation is far superior to Mr Ellis' solution, which is to use government policy as a mechanism to coerce developers who may have equally valid claims.
Arguably, increasing the supply of land available for development would greatly alleviate the housing affordability problem by reducing prices.
